Over Wide Flat Stock Tablesaw Cutting Jig

I had to cut 45’s on the ends of 4’ x 8’ stock on the table saw a while back. My saw is a left tilt, so the sharp edge would be ridding on the bottom of the fence. For whatever reason, I didn’t want to clamp a piece of ninety degree flashing to the fence or raise where the plywood landed on the fence. To solve the problem, I came up with this simple jig made from some aluminum flat stock I keep around for jig guide stock.

In the end, this gave me the forty-five degree edges I needed to make boxes for a store project.

Took me a couple of looks to figure it out. I assume the fence gets backed away after setting the plywood against it to square things up while you tighten the clamps? How do you compensate for drag on the far end of the plywood pulling it out of square with the blade?

Yep, the fence gets backed away after set up (second paragraph from the bottom).

Not sure what you mean by drag on the far end. Are you talking leverage, if you pushed from the far left on a wide piece? I push from just left of the blade, while running stock.

I never experienced drag, other than the guide running through the miter slot. The clamp holds it pretty tight. You could suspend a 4×8 sheet of 3/4 by the clamp.
